An Overview of DPL, MVL, Ternary Logic And CNTFET Technology for Contribution of Efficient Circuits

This paper analyses various circuits in CMOS and CNTFET technology. CNTFET technology along with Multi valued logic, complementary pass transistors, ternary logic and double pass transistor logic is far better than their CMOS counter parts. Present VLSI circuit designs can be potentially improvised through such techniques and circuits. This paper provides a glimpse of recent advancements in these techniques. Circuits such as Decoders, exact multipliers, inexact multipliers and logic gates, are reviewed in both the CMOS and CNTFET with various Logics such as Ternary, DPL, MVL logic. Exact multiplier’s energy consumption is reduced upto 6 times and energy efficiency is improved upto 35 times in inexact design, studied here. CNTFET showed tremendous improvements.
